APPARATUS FOR DELIVERING CLEAN WATER INTO CISTERNS FROM ROOFS OF BUILDINGS.

SPECIFICATION forming part of Letters Patent No.316,184, dated April 21, 1885.

Application filed December 30, 1884. (No model.)

To all whom it may concern:

Be it known that I, FaANgoIs SANOAN, of Thibodeaux, in the parish of La Fourche and State of Louisiana, have invented a new and Improved Apparatus for Delivering Clean Water into Oisterns from the Roofs of Buildings, of which the following is a full, clear, and exact description.

The object of my invention is to provide a simple, effective, and inexpensive'apparatus for insuring the delivery of rain-water from the roofs of buildings into cisterns or tanks in a comparative clean, pure condition, suitable for drinking, washing, or culinary purposes.

The invention consists in a water-receiving vessel located in the line of the pipe or leader which discharges the water into the main cistern or tank, said receiving-vessel having a tapering neck connecting with the water pipe or leader, and provided with a float-valve, which rises With the water and cuts of communication with the receiving-vessel. A perforated diaphragm is also provided for insuring the operation of the ball-valve, all as hereinafter fully described and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification,in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a sectional side elevation of a cistern and my improved apparatus for delivering water thereto from roofs, and Fig. 2 is a plan view with the delivery pipe or leader broken away and the cover of the dirty-water receiver in horizontal section.

The letter A indicates the pipeor leader which delivers the water from the roof of a building into the cistern or tank B,which may have any suitable form, size, and construction.

Near the cistern B, I place a smaller tank or vessel, 0, from the top or head of which rises the upwardly-tapering cover or neck D, which opens into the leader A, as at d.

A perforated diaphragm, which may be the head E of the tank 0, apertured, as at e, is provided, on which diaphragm a ball or float valve, F, will be supported when the waterlevel falls below the head.

I make the vessel 0 with a faucet, c, to draw the impure water from it when desired or necessary.

The operation is as follows: When rain is expected, any water remaining in the vessel G will be drawn off at-the faucet c, and when the rain falls and washes down the roof the water will first flow down the leader A and through the opening d into the vessel 0, and as this vessel fills and the water rises in the neck D the valve F will be lifted or floated until it closes the neck D, as in Fig. 1, and the water will flow through the leader A into the cistern B, the valve F preventing the water in tank 0 from mixing with the flowing water; hence no impurities can wash over from the tank 0 into the cistern B.

The size of the vessel 0 will be proportioned to the area of the roof, from which the Water flows down the pipe A, so that by the time the vessel 0 fills the dust and dirt shall have been washed from the roof into it, and the water running in pipe A past the vessel 0 into the cistern B will be comparatively clean and pure and suitable for drinking, washing, or

culinary purposes.

The perforated head or diaphragm E-which may be fitted in the neck D, if. desiredserves to support the valve F above the bottom of the vessel 0, thus preventing the valve from being held fast by accumulated sediment in the vessel should the water be wholly or almost wholly drawn from it, and the head E also prevents the valve F from being frozen fast in the bottom of the vessel; hence the valve is ready for action in all weathers.

Between showers the water in vessel 0 may be drawn off for irrigating or other purposes, so that very little water need be wasted.

I am aware that it is not new in apparatus of this kind to arrange, in combination with the main cistern, an intermediate receptacle for the purpose specified, and do not broadly claim such as of my invention, but only the arrangement described and illustrated. When the water falls in the auxiliary tank shown by me, the ball-valve will rest on the perforated diaphragm, and thus, being out of contact with the water, cannot freeze, and its operation is assured in all kinds of weather. It is also prevented from being retained by any sediment in the bottom of the vessel,which would be likely to occur if the ball-valve were allowed to fall to the bottom.-

2. The combination, with the main tank B and the slanting leader A, of the receiver or I 5 vessel 0, located in the line of the leader and constructed with the perforated horizontal partition E and the tapering neck D, connecting with the leader, and of the ball-valve F, working in the neck D above the partition E, 20 substantially as herein shown and described.
